Procedure

To a solution of 25 mg mitomycin A (0.071 mmol) in 2 ml. of anyhdrous methanol, 16.2 mg 2-aminomethylthiophene (0.143 mmol) was added with stirring. The progress of the reaction was checked periodically by TLC and the reaction appeared to be complete in 24 hours. Removal of the solvent by evaporation under reduced pressure gave a dark-blue residue. The residue was purified by preparative thin-layer chromatography using a pre-coated silica-gel plate (2 mm thickness) and acetone as developing solvent. The product was further purified by recrystallizing from a mixture of chloroform and hexane to give 20 mg (65% yield) of the desired product having a melting point of 92°-94° C. and providing the following analysis:
